belonging to the same general class. In 4or- 'der to accomplish this end I embed a body of fiber within the rubber tire in such manner that said fiber will materially increase its longevity and at the same time cause the wearto take place evenly and in such man- A ner that there-is no likelihood of injury to the tire due,l to the separation ortearing out of loose ends of the liber.' These objects I obtain as' hereinafter set forth, reference be which, 4

Figure'lis a 4vertical section of a well known form of pneumatic tire, showing my invention as applied thereto; and Fig. 2 is a vertical section of a solid tire constructed according to my invention.

In carrying out my invention I -form the wearing portion of the tire of a body of material consisting of fibers embedded in rubber or'e uivalent substance, which fibers are so place that they are substantially perpendicular to the wearing surface of the tire; there usually being'in addition other fibers extending at right angles to the lines of the 4Q main fibers for the purpose of holding these inposition during the process vof manufac--' ture and also .to give mechanical strength to the tire." It will be understood that the two `sets of fibers'are interwoven i'n order that the fabric resulting may be' of maximum .strenUtlL .r

' In liig. 1 of -the accompanying drawings,

A re resents a ,vehicle rim to -which the tire is applied,this tire in the present 5,0 instance `being shown as consisting of an inner tabel), a bjodr portion b-,u`suallyv it consisting of a plura y of plies of fabric anda/tread or wearing portion Ab.A It w' One object f my'invention is to provide a ing had to the accompanying drawings, iny

be understood that this latter is permanently attached to and may form a part of the body of fabric b', and my invention consists in embedding in this tread portion a series of fibers Zi so arranged as to be substantially perpendicular to the outside surface of the tread or substantially perpendicular to a line tangent to the surface of the tread.

These fibers extend between the fabric b and the outside surface of the tread,l their inner ends preferably abutting upon said fabric. In order that the fibers b3 may be suitably held in position during the manufacture of the tire, I preferably use a fabric having said fibers b3 for its warp and thc fibers b4 for its weft, so that these former fibers are properly spaced and held in position while being surrounded or embedded in the body of rubber forming the supportinO' structure or body of the tread bg.

t will be seen that under operating conditions the rubber will be protected by the fibers4 b3, which will naturally project slightly beyond the surface of the tread and take thegreater portion of the wear upon themselves. This protective material preferably consists of any desired form of vegetable fiber embedded in the body of rubber as above noted.

In F ig. 2, I have shown the invention as applied' to a solid tire, this being shown as in position upon a rim A carried on the felly C. The tire B is held in place by circumferentially extending wires a and, as before, consists of a rubber body having embedded within itV a series of fibers b3 which extend in lines substantially perpendicular to the wearing surface of the tire.

I claim as my invention:

A tire `consisting of a body of rubber, a mass composed of a series of long substantially parallel Vegetable fibersembedded in said rubber in a relatively compact body, said fibers extending .independently of .each

other and lying substantially perpendicular WM. A. Bann, WILLIAM E. BRADLEY.
